How will teachers' unions respond to robot teachers?

Many Americans seem upset that jobs are being "outsourced" overseas. Others are upset with Mexicans who immigrate, legally or otherwise, and are taking "American jobs." Both groups are worried about cheap labor "taking our jobs."

Actually, to date, robots have considerably improved the lives of almost everyone. Yes, robots have displaced workers on a lot of jobs, but goods made robotically are generally of superior quality and considerably cheaper, benefiting consumers. Even workers can reap the benefits, since those who remain in the increasingly roboticized factories earn higher wages from their increased productivity.

Now, out of Japan, comes the world's first robotic teacher. Saya, as the robot is known, has very limited capabilities. Currently she can only call roll, yell at students when they make too much noise, and lecture directly from the book-making her already as capable as many of America's worst teachers.

Watch out, teacher union bosses—robots are coming to take the jobs of your dues-paying members!
